Partial solar eclipse of 26 January 2047

A partial solar eclipse takes place on 26 January 2047. The Moon covers part of the Sun's disc but never all of it, because the shadow axis passes beside the Earth rather than across it. At greatest eclipse, 89% of the Sun's diameter is covered, seen from 62.7°N 112.1°E.

The simulator places the Sun, Earth and Moon at their true relative positions for this date and draws the shadow cones at real scale. You can scrub through the eclipse, drop an observer anywhere, and watch the umbra sweep the surface.

Local circumstances

All times are UTC. Contact times are computed for each city from the Besselian elements against the WGS84 ellipsoid, at sea level and without refraction.

C1 and C4 are first and last contact, when the Moon's disc touches the Sun's. C2 and C3 bracket the central phase. 522 of the 2,250 cities in the database see at least a 3% partial eclipse.

How these figures were produced

Positions come from astronomy-engine, a VSOP87/ELP implementation. From the geocentric Sun and Moon vectors the site computes Besselian elements — x, y, d, μ, l1, l2, tan f1 and tan f2 — and solves the observer's position on the fundamental plane against the WGS84 ellipsoid. Central durations agree with NASA's Five Millennium Canon to within about half a second. Full method and validation.
